More than 10,000 people have been killed and 40,000 injured in the war in Yemen, since bin Salman launched his Decisive Storm campaign to regain the country from Houthi control. Yemen is being ravaged by an outbreak of cholera that has infected 500,000 people.

Two-thirds of its population - more than 18 million people - need humanitarian assistance and more than seven million are suffering from malnutrition.
